Abstract
The invention provides a driving method, driver circuit and designing method of driver circuit for in-cell touch display panel. The driving method comprises: Step: connecting all horizontal scan lines of the touch display panel to a first GOA circuit, the first GOA circuit performing display scanning according to a preset timing sequence; Step: after completing each time of TP scanning according to preset timing sequence, a first horizontal scan line in a following scanning according to preset timing sequence still connected to a second GOA circuit, the second and first GOA circuits synchronously performing display scanning to the first horizontal scan line. The driving method, driver circuit and design method of driver circuit for in-cell touch display panel provided by the invention solve the dark line problem appearing in time-sharing scanning between display and TP terms for in-cell touch display panel, and improve display quality.
